Passing variable to href django template


I have some problem and maybe I can give an example of two views below what I want to achieve.

class SomeViewOne(TemplateView):
    model = None
    template_name = 'app/template1.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        # The downloads view contains a list of countries eg France, Poland, Germany
        # This returns to context and lists these countries in template1
class ItemDetail(TemplateView):
    model = None
    template_name = 'app/template2.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        countries_name = kwargs.get('str')
        The view should get the passed "x" with the name of the country where I described it 

Then on the page I have a list of these countries.
After clicking on the selected country, a new tab should open and show a list of cities in the selected country.

So I am using in loop template1.html as below

{% for x in list_countries %}
      <a href="{% url 'some-name-url' '{{x}}' %}" class="target='_blank'">{{ x }}</a><br>
{% endfor %}

I can’t pass "x" this way. Why?

The url for the next view looks like this

path('some/countries/<str:x>/',views.ItemDetail.as_view(), name='some-name-url'),

And I can’t get that ‘x’ given in the template in the href

You don’t need pass that variable with single quotes.

<a href="{% url 'some-name-url' {{ x }} %}" #Just removed single quotes from variable x.

And see if it shows on template

If Manoj’s solution doesn’t work, try removing the single quotes AND {{ }}. In my program, my integer doesnt need to be wrapped with {{ }}, so maybe neither does your string.
I have this in my code:

{% for item in items %}

        <div class="item-title">
          {{ item }}<br>
        <a href="{% url 'core:edit_item' %}">Edit {{ item }}</a>
{% endfor %}

It works just fine. Try:

<a href="{% url 'some-name-url' x %}" class="target='_blank'">{{ x }}</a>

There are several mistakes such as:

  1. It should be only x in url tag neither {{x}} nor '{{x}}'

  2. you have passed the value as x in url params (some/countries/<str:x>/) and accessing it using kwargs.get('str') which is not correct it should be kwargs.get('x').

  3. Also you are not including variable countries_name in context and not even returning context.

Note: Assuming that you are already getting some companies in template1.html template that’s why you are running loop.

Try below code:

class ItemDetail(TemplateView):
    template_name = 'template2.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['countries_name'] = self.kwargs.get('x')
        return context

Template1.html file

{% for x in list_countries %}
      <a onclick="'{% url 'some-name-url' x %}', '_blank')" style='cursor:pointer;'>{{ x }}</a><br>
{% endfor %}

Then you can this countries_name value passed from template1.html in template2.html.


<p>The clicked country is {{countries_name}}</p>
